Abstract
The invention relates to an external-backwashed magnetic-powder-filler permanent-magnet fine filter. According to the external-backwashed magnetic-powder-filler permanent-magnet fine filter, at least one filtering unit is arranged in a filter cartridge, and a filtering sieve bed is arranged above each middle sealing partition plate; a hydraulic motor is arranged at the upper part of each filtering sieve bed and drives a rotary slurry distribution pipe to rotate relatively to a tray of the filtering sieve bed; paramagnetic powder is tiled on each tray; when hydraulic jacking rods are in a contraction state, the paramagnetic powder is compacted on the trays under the action of magnetic attraction force of permanent magnets, so that a water-permeable magnetic powder layer with water-permeable microporous passages is formed on each tray; the water-permeable microporous passages have such a pore size that only water molecules and soluble salt ions are allowed to pass through and non-dissolved impurity groups are sufficiently prevented from passing through; water through holes are formed in the trays. The external-backwashed magnetic-powder-filler permanent-magnet fine filter has the advantages that filtering sieve trays can be automatically flushed without manual intervention, and the operating efficiency is high.
